SF6804ZZ Bearing Product Overview & Core Advantages
The SF6804ZZ is a metric flanged ball bearing designed for precision applications requiring compact design and reliable performance. This single row bearing features shielded construction for contaminant protection while maintaining excellent radial load capacity. Manufactured with stainless steel rings and cage combined with chrome steel balls, it delivers superior corrosion resistance and durability. The integrated flange provides secure mounting and precise positioning in compact assemblies, making it ideal for applications where space constraints and high rotational accuracy are critical requirements.

SF6804ZZ Bearing Structural Features & Performance Benefits
Compact Flanged Design: The integrated flange (35mm OD, 1.5mm thickness) allows for simplified mounting and precise axial location, reducing assembly complexity and improving positional accuracy.
Enhanced Load Capacity: With a radial dynamic load rating of 813 lbf and static load rating of 498 lbf, this bearing handles substantial radial loads while maintaining stable operation.
Precision Performance: Manufactured to ABEC-1 tolerance class with controlled radial internal clearance (C0: 0.002-0.013mm), ensuring consistent running accuracy and minimal vibration.
Corrosion Resistance: Constructed with stainless steel components throughout (rings, cage, shields), providing excellent protection in harsh environments and extending service life.
Optimized Speed Capability: The limiting speed of 18,900 rpm is achieved through precision-ground 3.5mm balls and efficient 13-ball configuration with stainless steel cage.
SF6804ZZ Bearing Typical Application Areas
- Precision instruments and measuring devices requiring high rotational accuracy
- Small motors and miniature drives in industrial and commercial equipment
- Medical equipment components where corrosion resistance and reliability are critical
- Office automation devices including printers, scanners, and copiers
- Robotic components and automation systems requiring compact, precise bearing solutions
